wnL'r-BEA'rIne MACHINE;

Specification of Letters Patent.

Patented May 4, 1909.

Application filed September 17, 1908. Serial No. 453,517.

One object of my invention is to provide a machine for beating out the welt of a. shoe during the manufacture thereof with a view to not only remove any wrinl :les or irregularities which may exist, but also for the purpose of stretching the welt transversely or away from the shoe and thereby increasing the width of the welt. I

I further desire to provide a relatively uncomplicated and easily operated mi'whine which shall simultaneously pound or hammer a welt and apply tension thereto in order that it may be flattened and increased in width, at the same time providing a device for supporting the welt which is ca able of being moved into and out of the pat 1 of the beater arms.

These objects and other advantageous ends I secure 'as hereinafter-set forth, referones being had to the accompanying drawings, in which I Figure v1, is a side elevation of my improved machine; Fig. 2, is a front elevation of the machine illustrated in Fig. 1, part of the same being a section on the line 2-2, of said figure; Fig. 3, is a sectional elevation illustrating one of the beating arms inthe position occupied just before it is drawn off of the welt; Fig. 4, is a side elevation of a special form of anvil; Figs. 5 and 6 are respectively a front and side elevation of the preferred form of. anvil employed as part of my invention; and Fig. 7, is a perspective view of the shield used as part of my invention.

In the above drawings, A represents the frame of the machine, the upper. portion of Which is provided with bearings for the support of a horizontal shaft, 1), and which also is provided with a forwardly extending boss a in which is mounted a statiqliary shaft or pivot pin'c. On the-shaft?) is mounted a pulley b driven from any desired source of 7 power and said shaft also has fixed to it a pair of parallel disks 1) between which extend any suitable number of pivot pins or spindles b. On each of these latter is mounted a beater arm-c and eac'harm-has fixed to 'it a spring b engz'rging a pin 1)" also 1 extending between the disks; the arrangement being such that said springs tend to maintain said arms projecting in radial lines relatively to the shaft 7) while leaving them free to be turned on the pivot pins If. ht the same time these springs prevent too great a rebound of the beater arms when they istrike upon a welt under treatment and said arms are held in position to deliver square flat blows by stopslf so placed as to prevent them from moving from their radial positions in one direction under the normal action of their springs. The shaft 1) is turned in a definite direction indicated by the arrow Fig. 2 and the forwardfaces of the beater arms are preferably roughened or toothedas indicated at 0' so as to enable them to engage and forcibly pull awelt operated on.

Mounted upon the supporting shaft or spindle a is a Welt supporting arm or anvil I) having two stops (:5 and d mounted upon the base a whereby its possible oscillation upon Said shaft is limited. At one end of its are of movement its extremity, which may be flat as shown in Figs. 2 and 3, or preferabl rounded as shown in l i 5, comes in such position as to be engaged by the toothed or roughened ends of the beater arms 0; while at its other extreme position it is well out of the path of said arms, so that when not in use, the machine runs noisclessly. This anv'il is preferably constructed as shown at l) in 5 and 6;that is, itsl'ree end is curved and extended at an angle to. its length to form a sharp edge capable of engagingthe Welt for a nnixirnuni transverse distance. The end section (1 is also made separate from the body of the anvil, being slotted and held to said body by screws d passing through the slot so as to be free to move longitudinally to a limited extent. A block of rubber or other resilient substance (i is placed between the inner end of the part (1 and the body of the anvil, with the result that blows struck on the anvil are cushioned,

A shield G formed of a properly shaped length ,ofsheet u'u'tterial ispivoted to the movable part of the anvil so {rs-to extend blows of the beater arms. A spring 9 normally retains this shield in the position shown inithe drawings, and 1t is pulled by the action dotted lines against the force of said spring, so that as a consequence a welt under treatmepti qs'further stretched.

over the end thereof and directly receive the 01'; the beater arms into the position indicated Under operating conditions 11. partially made shoe '4 is so manipulated that its pro jecting Welt e is caused to rest upon the Hat end. of the anvil D or D which is then moved from the position shown in dotted lines in lTi 2, to that shown-in full lines to bring the We t into the path of movement of the beater arms. The shaft 7) and the disks 1) being rapidly turned, these arms are successively brought into engagement With the Welt, each arm striking said Welt so as to compress it against the end of the anvil and then turning on the pivot b so as to pull or stretch the Welt transversely away from the shoe. in so doing each arm moves from the position shown in Fig. 2 to the position sh own in Fig. 3, and is finally drawn oh of the Welt and past the anvil. Under the action of centrifugai force as well as of its spring I? each arm is immediately thereafter restored to its origi- I nal radial position. The shock of the blows is taken by the resilient blocks (1 and before noted the shield aids in applying tension to the Welt.

When the shoe hes been turned to bring all portions of the Welt successively under the action oi the beater arms, the anvil is brought to the position indicated in dotted lines and the shoe removed. In order to faciiitate the feedin of the Welt I preferably incline the top suriace oi the anvil as Well as that of the beater arms as shown iii-Fig. 4, so that their operative faces are inclined relatively to the plane of movement of said arms.

By the above noted action the Welt is flattened and stretched outwardly or away from the shoe to a marked extent its Width b'cin 7 Z? increased to such an amount that it is pos sible to employ a narrower well; than would otherwise be permissible. it will be noted that the action of my improved machine is such that the Welt is flattened and stretched transversely; that is to say, the puli ou the wait tends to draw it away from the shoe and as a platter of fact, does increase its Width.

In some cases I may heat the arms 0 as Well as the anvil in order that the Wet and pliable Welt may be dried out and hardened preparatory to its being cemented to the sole blank and For this purpose I mount in said parts suitable electrical or other heating apparatus. In the present case I have ilius trated coils of wire H and H huving suitable terminals free to be connected to a source of current.

If desired, the springs b may be omitted, as in many instances the centrifugal force is sufiicient to maintain the beating arms in their radial or extended position.

I claim:
